Several P-series droidekas remained on Lok after the Trade Federation utilized it as a testing zone for their assault on the planet of Naboo, in addition to other B1 model droids.

Swift and deadly, the P-series was nevertheless obsolete by the time of the Battle of Geonosis, during which the more advanced W-series was also deployed.

Although it could not use its deflector shield generator while in "wheel" mode, the P-series became largely invulnerable once it unfolded into its upright firing stance. It even stymied the resourceful and powerful JediQui-Gon Jinn and Obi-Wan Kenobi, who abandoned their immediate task and fled when faced with these "destroyers" aboard Saak'ak. The deflector shield generators, however, were not immune to heavy artillery, as demonstrated when Anakin destroyed three P-series droids with a Naboo starfighter,[1] as well as the Republic Gunships making short work of them when the Grand Army of the Republic arrived at the stadium to save Jedi during the Battle of Geonosis at the start of the Clone Wars.[2]
